 (1D) is an extension connection circuit.

In the still image file means (1) and the whole apparatus, first, when a still image is captured, the following is performed.

That is, a video signal supplied to any of the input / output circuits (14a) to (14f) is subjected to a predetermined A / D conversion and supplied to the video bus (11), and the signal of the video bus (11) is supplied to the interface circuit ( Displayed on a high-resolution color display (202) through 16).

Further, in the still image taken in this case, an index image in which pixels are extracted at a predetermined ratio is formed together with a full image of all pixels of one frame, and these still images are searched together. And a descriptor including an arbitrary classification code for the purpose. Then, these two still images and descriptors are written in the memory device (1A) in a predetermined format. As a format, the descriptor, the full picture, and the index picture are written in independent areas, and the corresponding addresses of the full picture and the index picture are provided in the descriptor. The above-mentioned index image may be formed by connecting arbitrary hardware to the video bus (11), or may be processed by software in the CPU (17) and the connection circuit (18). The memory device (1
The still image captured in A) is a MO disk drive (1
03) etc. and can be saved and this MO disk can be removed and used in other similar devices.

The still image thus captured is edited as follows.

That is, FIG. 3 is a functional block diagram. For example, when an MO disk on which a plurality of still images are written as described above is supplied to the drive device (103), the MO disk is first used for retrieval from descriptors on the disk. A database with classification codes is formed on the workstation (2) [2
1] is done. An image based on this database is displayed on a color display (202), and a search [22] is performed on the color display (202) with a keyboard (203) or a mouse (204). ), The corresponding still image descriptor is read from the drive device (103) [11]. The descriptor is analyzed [12], the addresses of the index picture and the full picture are stored [13], and the index picture is read [14] from the drive device (103) according to the analyzed address, and the read index is read. The image is transferred to the memory device (1A). The index image transferred to the memory device (1A) is further transferred to the interface circuit (16).

Here, the interface circuit (16) is provided with, for example, an image memory (16M) corresponding to all the pixels of the color display (202), and receives a signal supplied from the CPU (201), for example, as shown in FIG. Background image is formed. The above-described index images are sequentially written and displayed by the address control [15] for each of the shaded ranges in the upper half of the background image. By writing all the searched index images to the memory device (1A) once, for example, 13
When there are more than one copy, access to another page of the display can be performed at high speed.

On the other hand, the lower half of the background is shaded
Is provided. Then, while an index image is displayed in each of the above-mentioned ranges, an arbitrary cursor (not shown) is moved into a desired still image range with a mouse (204) or the like, and an arbitrary key operation or the like is performed there. Then, the still image corresponding to the range is determined [23] at the workstation (2), and the addresses of the full image and the index image of the desired still image are selected from the addresses stored in accordance with the determination [23]. The full picture and the index picture read [16] from the drive device (103) are written to the memory device (1A), and the index picture is written to the address of the memory (16M) corresponding to the range. It is rarely displayed.

By repeating this operation,
, An index picture of a desired still picture is sequentially displayed, and the index picture and the full picture are sequentially stored in the memory device (1A).
Is written to.

During further editing, for example, the above-described cursor is moved to the position of an up-down arrow displayed on the right side of the range of the display surface to perform an arbitrary key operation or the like there. At (2), the direction of the arrow is determined [23]. Further, according to the determination, when the arrow is downward, a still image before the still image in the range is read out by the memory device (1A), and when the arrow is downward, 12 still images after the still image in the range are read out and read in the image memory (1A). 16
M) is written to addresses in the range ~.

Thus, by moving the cursor to the position of the arrow on the display surface and performing the operation, the pages before and after the page being displayed are displayed as 12 pages of still images as one page, and the desired page is displayed. Still images can be taken out very easily.

Editing is performed in this manner, and the packets of the still images arranged in the desired transmission order are stored in the memory device (1A).
Will be completed. This packet is also sent to the drive (10
You can also transfer to 3) and save it to MO disk.

Further, when transmitting a packet of a still image edited as described above, the following is performed.

That is, in the above-described device, for example, the input / output circuit (14
a) is for transmission, and a monitor receiver (not shown) is connected to the input / output circuit (14b). Further, transmission is performed in a state where the edited still image packet is stored in the memory device (1A). When the workstation (2) first issues a transmission instruction, the first still image of the packet is transferred to the input / output circuit (14a) for transmission, and the second still image is transmitted to the input / output circuit (14b). And displayed on the monitor receiver. Next, in this state, when the transmission instruction is issued again from the workstation (2), the second still image of the packet is transferred to the input / output circuit (14a) and transmitted. The data is transferred to the input / output circuit (14b) and displayed on the monitor receiver.

The still images of the packets edited in this way are sequentially transmitted. In this case, a still image to be transmitted next is displayed on the monitor receiver, and if the next still image is not needed after seeing this display, the next still image is transmitted by an instruction from the workstation (2). Processing such as deletion can also be performed.

Thus, according to the above-described device, the still image before editing is displayed on one of the divided display surfaces, the still image after editing is displayed on the other, and the still image before editing is arbitrarily changed. Thus, editing of a still image and the like can be performed extremely smoothly.

In the above-described apparatus, when an arbitrary still image is selected in the range, the index image in the range is deleted, index images in the following ranges are sequentially moved up and displayed, and the first index of the next page is displayed. The image may be displayed in a range.

The division of the display surface is not limited to the above-described upper and lower divisions, but may be divided into left and right divisions.

Further, in the above-described apparatus, the still image may be provided with a key image (one bit per pixel) for performing so-called key combination, in addition to the full image and the index image.
